| Abstract: | The crystal structure of the La(DMSO)6(H2O)PW12O40] · C2H5OH complex (I) (where DMSO is dimethyl sulfoxide) is determined by X-ray diffraction analysis. The coordination polyhedron of the La atom is a distorted
tricapped trigonal prism in which two cap sites are occupied by oxygen atoms of the heteropolyanions. For these atoms, the
La-O distances 2.760(9) and 2.801(9) Å] are considerably longer than the other distances ranging from 2.441(10) to 2.569(10)
Å] in the environment of the La atom.
